How to pass Journey Configurable form attribute value to BI Publisher Report?

Hello,

We have requirement to create an acknowledgement of courses (selective) attended and the date attended, publish it to DocumentReport.

We have configured a Form (PER_PERSON_ALLOCATED_TASKS_DFF) with certain attributes containing Attributes for courses and when they were attended (date attributes).
Configured a Journey Task of Advanced type with 1. Form 2. Signature 3. Report
We want to have the field values entered by the performer in the form to be passed to the Report so that it can display the same with signature and get posted to the Document Records.
It should be possible to do it as a 2-step process. We can generate the report after the data is saved to the database on the Task form.
